Ho hum; today's Tour de France stage was parade from Cambridge into download London, where Marcel Kittel finished off the field easily in a bunch sprint. The GC was unchanged, and on we go into France. There were huge crowds in England lining the road nearly the entire way - again! - but they didn't have much of a race to watch today.

Tomorrow the field crosses the channel into France for another flat stage, a warmup before the Paris-Roubaix-like cobbles of stage 5. Stay tuned...

Today I rediscovered for the Nth time the value of the three-hour rule*: it takes three hours to get anything "done", especially if that thing is something which requires concentration, like programming. And during that three hours it's best disable all interruptions; don't check email, take phone calls, send texts, etc. Three hours.

A good day includes at least one three hour window, and a great day includes two :) Today ... was a good day. Tomorrow? We'll see :)
